TYPE-LINE SETTING AND CASTING MACHINE.

Application filed May 27, 1926, Serial no.

The invention relates to type line setting and casting machines in which the matrices move on endless wires. In machines of this type feeding men'ibers move matrix bar-3 return immediately to their initial position to collect a. fresh number of matrix bars which have occupied casting position in the meantime. The constructionalproblems involved in correctly moving the feeding members are particularly dificult because the matrixbars must be moved substantially along a semi-circle and simultaneously raised so that they may'enter the magazine.

The present invention solves the problems involved by providing two sets of such mem bers. The members of the first set, hereinalter referred to as pusher-s or push lingers, are reciprocated about a stationary spindle through 180. These pushers move forward with the collected oust matrix bars and deliv r them to the seconu set, hereinafter referred to as the drivers, The latter are linearly reciprocat d. Both when covering their return journey are moved at a suitable point out of the path they follow on their outward or working travel for the purpose of escaping the matrix bars fed in position for further (lelivery. At the end of the return or idle journey the pushers and drivers move into their working path and are then behind the next group of matrix bars to be moved along.

A construction of the device according to this invention is illustrated in the accompanying drawings in which:

Figures 1 and 2 illustrate two positions of angular-1y moving pushers; as Figure 3 is a horizontal section on line 33 of Figure 1 showing the pushers and drivers in plan;

Figures 4 to 6 show on a larger scale three positions of the. connection mechanism between a vertical spindle and the pushers;

Figure 7 is a section along line 77 of Figure l; 7

Figure 8 is a section are 4, and Figures 9 and 10 are sections on line 9-9 of Figure 1, the drivers being shown in two positions.

trix bars 1 are moved on superposed wires, three of which are shown in on line 8-8 of Fi along a path leading to the magazine and I sets however 112,133, and in Germany August ,17, 1925.

the construction illustrated. As shown in Figure 3, these wires form a closed or endless path. After being cast at A, the matrix bars 1 are moved in the direction of the arrow (Figure by a rake-like feeder 3 which is not part of the invention. The matrices are then pushed along by push members 5 moving about a vertical spindle 4 while the said matrices simultaneously rise and reach the position shown in Figure 2 from that shown in Figure 1. The set of matrix bars is now engaged by drivers reciprocated along a straight path and rises further until it reaches the highest point, for example B in FigureB. At this point the matrix bars are distributed over the magazine (not shown).

"he vertical spindle 4 is angular-1y .r ciprocated through 180 in a suitable way by the actuating mechanism of the machine. A red 9 carrying the push fingers 5 is connected to the said spindle by links 7 8, the lower end of the said rod resting on a helical slideway 10 the pitch of which is that of the guiding wires The push members 5 therefore rise from the position of Figure 1 into that of Figure 2 together with the matrix bars.

The spindle 4; is rigidly connected to a guide member having two oppositely disposed guide plates 11, 12 (Figure 8) between which two flat rods 13, 14 are guided which are adapted to move parallel to the longitudinal axis of the spindle 4c. The links 7 and 8 are connected to these flat rods 13, 14 through the medium of supports 15 and 16. The upper end of a helical spring 17 surrounding the spindle 4 bears from below on the flat rods 13 and 14 or on the support 15, the lower end of the spring being in contact with a cone member 18 movably mounted on the spindle 4. A slide 20, movable longitudinally on the spindle l and partaking in the rotation thereof, is located under the cone member 18 and is guided by a sleeve 19 not connected to the said cone member 18. The arms 21 supporting the link 7 are pivoted on the said slide which moreover carries a bracket- 22 suitably engaged by the lower end of a spring catch 2st pivoted at 23, the upper end of the said catch being adapted to engage the guide plate 11 from below. The guide plate 12 carries a spring catch pivoted at 25 and having a projection 27, the said catch co-operating with a cam 28 secured to the frame of the machine.

The device works as follows:

The spindle 4-. turned through 180 by the mechanism of the machine as soon as the push fingers 5 engage behind the matrix bars fed from the setting point A (Figures 1 and 4t) the rod 9 rising on the siideway 10. The links T. 8 and the arms 21 likewise rise until they reach the position shown in Fig ures 2 and 5. The rod 9 has thus moved along the path C on the srideway 10. (Figure 3.) The slide 20 togetner with the sleeve 19 and the cone 1J1(3111l.;8t' 18 are moved upwardly on the spindle by the arms 21 so that the spring 1'? is compressed. Compression of the spring is possible mving to the circumstance that at the beginning of the angular motion the catch springs under the guide plate 11 to prevent the support 15 fron'i being pushed upwards. together with the fiat rods 1 1+1, by the spring 17 under compression. hen the rod 9 reaches its highest position the projection 27 of the catch 26 springs into engagement under the cone member 18 and urnily holds the lower end of the compressed spring in position.

After the matrix bars thus pushed along are delivered to the drivers 6 the spindle t turns in the opposite direction, the rod 9 with the pusher-s 5 moving first along the path C towards the end of which the said rod moves along the path D. This change of travel is essential, as otherwise the push fingers 5 would impinge against the foremost matrix bar of the batch of such bars fed in the meantime from the setting point A, whereas the said fingers should engage behind the rearn'iost bar. The rod 9 is moved out of the path C by releasing); the catch 24:, and through the medium of the locking gear-l8, 27. The lower end of the compressed spring 17 is held in the raised position by the said gear whilc th-e now released catch 2i allows the upper end of the spring to move upwards. While the push fingers 5 are returning to their initial position the slide 20 .e'lides downwards on the spindle 4t; towards the end of this move ment the bracket 22 presses on the tapering lower end of the catch 2% to move the latter clear of the guide plate 11. The upper end of the compressed spring 17 can now rise (Figure 6) so that the rod 9 movesinto the path D and occupies a position 29 she vn in dotted lines in Figure 1. At this moment the cam 28 releases the catch 26 so that the spring 17 expands downwardly and the flat rods 13 and 1 t drop by gravity together w th the su )port 15, the rod 9 hein; moved along a straight line on the path (Fi 5 re The push fingers are now in a positic-.1 in which they engage behind the rear- 30 (Figures 0, 9 and 10) pivot-ed about a point 31 at the rear of the frame of the machine. The front end of this rail has a stem 32 axially movable on the frame 33 of the machine, and constantly urged by a spring 34: to lie parallel to the guiding wires 2. A cam disc mounted on the spindle & and presses against a tappet 3t") guided along a straight line. A double-arn'ied lever 38 is pivoted at 37 on the said tappet, one end of the said lever nearing against a plate 39 carried on the stem The spindle l carr'es a spur 40 adapted to press against the lever 38.

Vi hile the pusher-s 5 are moving forward the cam disc 35 pushes the tappet 36 forward so that with the aid of the lever 38 the stem 32 is moved out of the position of ligure 9 or Figure 3 (shown in full lines) into the posit on of Figure 10 (shown in dotted lines in Figure 3). At the same time a spring 41 pulls the lever 38 so that its front end in'lpinges against the plate 39., and the drivers 6 are moved out of the path of the matrix bars. As soon as the push fingers 5 reach their forward outermost point. the spur 4O presses on the lever and moves it clear of the plate 39, with the consequence that the drivers 6 are moved by the spring 3% into the path of the matrix bars and engage behind the rearmost bar.

The spring then m ves the tappet 36.

back to its initial position the front end of the lever thus impinging again against the plate 09.
